Source | Produced by bacteria, cobalamins (hydroxocobalamin and cyanocobalamin) are analogs of vitamin B12 that differ only in the beta-ligand of the cobalt; Found in fish, meat, liver, and dairy products, but not in plants; Also occur naturally in soil, water, activated sewage sludge, and manure. |

Mechanism Of Toxicity | Vitamin B12 is used in the body in two forms: Methylcobalamin and 5-deoxyadenosyl cobalamin. The enzyme methionine synthase needs methylcobalamin as a cofactor. This enzyme is involved in the conversion of the amino acid homocysteine into methionine. Methionine in turn is required for DNA methylation. 5-Deoxyadenosyl cobalamin is a cofactor needed by the enzyme that converts L-methylmalonyl-CoA to succinyl-CoA. This conversion is an important step in the extraction of energy from proteins and fats. Furthermore, succinyl CoA is necessary for the production of hemoglobin, the substances that carries oxygen in red blood cells. |
